This invention relates to improvements in check row planters and has particular relation to means for controlling the operation of the seed dropping mechanism of the planter,

an object being to provide means'for automatically dropping the seed grain at proper intervals without the use of a check row wire or cord. 3

Another object of the invention is the proic vision of means as above stated which may be easily and accurately adjusted, and which will'maintain proper adjustment, the char-' acter of the mechanism being such as to permit of the machine being turned at the end of 15 the rows so as to maintain proper spaclng of the seed in succeedingrows.

VViththe above and other objects in view,

the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings I Figure 1 is a plan view of a check row planter embodying the invention.

' Figure 2 is an enlarged fragmentary-elevation of the clutch for controlling the dropping mechanism. Y

Figure 3 is a vertical sectional view of the 30 same. Figure 4: is an enlarged fragmentary section on the line 14t of Figure 1.

Figure 5 is an enlarged section partly broken away illustrating the means for lock- :55 ing the driving wheels to the axle.

Figure 6 is a detail elevation of the gage frame, the stakes and controlling means therefor. V

Figure 7 is a diagram illustrating the path of the wheels of the machine when the latter is turned at the end of the rows.

Referring to the drawings in detail wherein like characters of reference denote-corresponding parts, the machine as shown'com 45 prises a suitable frame 10 which connects the machine proper with the frame 11' carrying the seed hoppers 12.v These hoppersare of the usual or any preferred type and carry suitable dropping mechanism controlled by 59 a rock shaft 13. The ,hoppersmay also be vreferred to.

'ries a pair of oppositely disposed segmental provided with suitable agitators operated from a shaft let which is driven by a chain and sprocketdrive 15 from the axle 16 of the machine. y v Mounted upon the 'axle 16 are driving wheels 17 the latter includinghubs 18 which" are engaged by spindles 19, the latter be ing freely rotatable upon the axle '16; The spindles 19 are provided with toothedextensions 2O which abut toothed sleeves- 21. These sleeves are keyed or otherwise secured upon the axle'16. slidable upon the sleeves 21 and the toothed extensions are internally toothed collars 22, the outer peripheries of these collars being provided with annular grooves 23 which receive lugs 24 provided at the inner ends ofv shifting levers 25. The levers 25 are mounted for pivotal movement as shown at 26, the pivotal supports for these levers extending from housings 27 which enclose the parts just This is plainlyiillustrated in, Figure 5 of the drawings. The levers25 are connected by means of a rod 28 and the latter has connected thereto a foot pedal 29, so that the operator of the machine may press upon this pedal to move therod 28 longitudinally and shift the levers 25. By reference to Figure 5 of the drawingsit will be seen that when the collars 22 are in the position shown, the spindles 19 and consequently the Wheels 17 are free of the axle 16, but'when the collars are shifted to the right of said figure so as to engage both the teeth of the sleeves 21 and the extensions 20, the spindles will be locked to the axle and the axle will rotate with the wheels. 7 I

For the purpose of operating the shaft 13 of the dropping mechanism, the axle 16 car- 9O gears30. These gearsare carried by a sleeve 31 which is slidable longitudinally of the axle and which carries a clutch member 32 arranged to engage a clutch member 33. The sleeve 31 rotates freely upon the axle when the clutch members are disengaged, while the clutch member 33 is pinned or otherwise secured to the axle as shown at 34. A sleeve 35 surrounds the axle 16 within the sleeve 31 and a spring 36 is interposed between the [32 ,and33 thereis provided a cam a l which 2 5 Pivotally mounted as shown at 38 is an arm 39 whose outer end carries a segmental gear 40. This gear is arranged 1n the path of the segmental gears when the clutch members 32 and 33 are engaged, so that when the sleeve 31 is locked upon the axle, the segmental gears 30'will alternately engagethe segmental gear 10 to rock the arm 39. Rigid With the arm39 is an arm A1 and connected to this lastmentioned arm is one end of a rod 42;.jwhose opposite end is connected to an Qarm 13 which is rigid with the shaft 13 ThL1s, when the axle 16 is rotated, theshaft 13' will be, intermittently: rocked to actuate the, dropping 'mechanism within the seed hoppers 12; 1

In order to separate-the clutch members straddles the clutch and isguided between annular .jfianges 35 and :36? "carried respectively by: the clutch members 32 and 33; Extendingfrom'this cam is an arm 45 which is pivotally secured as; at 46kto a pivotally mounted hand leverl l'i'. This' hand lever maybe pivotally moved to raise orlowerthe cam 1 1 to permit the clutch, members 32 and 33;to.engage or disengage these members. The Ilever 39 isheld adjusted position by and against theshoe 52. "The r0d51 is slid-f means of a spring'actuatedd gtS which is 1 I iar flanges 35 and 36 ,Wltl1 hke numbers as adapted to engage a toothed segment 49;

Secured to the arm l5 is an arm 50 through ablerthrongh the arm 50 and carriesat its outer end a head 5-1' so as toprovide a stop. It willbe apparent-from the foregoing de-- scription; and accompanying drawings that with the axle 16 lockedto the wheels 17, the

' axlewill-berotated and with theclutch members 32 and 33 engaged, the segmental gears 30 xwill alternately engage; the segmental: gearqlOand the shaft-[13 Willllfi intermittently rocked to operate the seed droppingmechanism; 1 By ineans" of the :lever 47, the

clutch members 32 and 33 may be separated,

continued inward movement of i the separatmg cam 441 moving thebrake shoe 52 into engagement with the periphery of the annular I flange 35 so as to holdthe sleeve 31andconsequently the segmental gears 30 against rotation.

Secured to the frame 10 isa gage frame 55. andslidingly mounted in guides "56 at oppo site ends of this frame are pinsor stakes 57. These'pins or stakes are normally held elevatedby meansof springs 58 and have secured to their upper ends an arm 59 which is pivotally mounted as shown at 60. Rigid with the arms 59 are operating levers 61 which carry spring dogs 52 arranged to engage toothed segments 63, so that by operating the levers 61, the stakes 57 may be moved into and out of engagement with the ground 3 i V When the machine reaches the ends of the rows indicated by the dotted lines a in Figure 7 of thei drawings, one of the stakes 57 (the; left hand stake) is forced into the groundiat the point indicated at b. The left hand wheel 17 is disengaged from the axle 16 and the righthand wheel engaged. In turning, the left hand wheel will follow the dotted line indicated at c and the right hand wheel the line indicated at d] The circumference of the wheels 17 is such-that in making the turn the outside or right hand wheel will make two and one-half revolutions.

Thisis assumingthatthe rows are forty and one-third inches'apart and the wheels sevshown in Figure 2 and when these numbers correspond, proper adjustment is made.

' The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appended claims;

Having described the invention what is claimed is 1. In a check row tion with the driving'wheels and axle, of
